160-552: Is as a gasoline-additive for increasing octane number . Dimethoxymethane can also be used for blending with diesel. Another useful application of dimethoxymethane is to protect alcohols with a methoxymethyl (MOM) ether in organic synthesis. Dimethoxymethane can be activated with phosphorus pentoxide in dichloromethane or chloroform . This method is preferred to the use of chloromethyl methyl ether (MOMCl). Phenols can also be MOM-protected using dimethoxymethane, p -toluenesulfonic acid . Alternatively, MOMCl can be generated as

200-532: Is different from Wikidata All article disambiguation pages All disambiguation pages Dimethoxymethane Dimethoxymethane , also called methylal , is a colorless flammable liquid with a low boiling point, low viscosity and excellent dissolving power. It has a chloroform -like odor and a pungent taste. It is the dimethyl acetal of formaldehyde . Dimethoxymethane is soluble in three parts water and miscible with most common organic solvents. It can be manufactured by oxidation of methanol or by

220-467: The anti - anti conformation, while the gauche - anti and anti-gauche are intermediate in energy. Since it is one of the smallest molecules exhibiting this effect, which has great interest in carbohydrate chemistry, dimethoxymethane is often used for theoretical studies of the anomeric effect. Industrially, it is primarily used as a solvent and in the manufacture of perfumes, resins, adhesives, paint strippers and protective coatings. Another application

360-464: The reaction of formaldehyde with methanol. In aqueous acid, it is hydrolyzed back to formaldehyde and methanol. Due to the anomeric effect , dimethoxymethane has a preference toward the gauche conformation with respect to each of the C–O bonds, instead of the anti conformation. Since there are two C–O bonds, the most stable conformation is gauche - gauche , which is around 7 kcal/mol more stable than
